To all 'whom 'it may concern:

Be it known that we, TADE Z. MALLY and ANDREW PELz, both citizens of the United States, andboth residing at Chicago, .in the county of Cook and State of Illinois, have invented certain new and useful Improvements in. FloorScrubbers and Polishers, of

which the following is a specification.

This invention relates to a'floor scrubber and polisher which is adaptedfor use in a manner similar to that 1n .which carpet sweepers are ordinarily used; and the object of the inventionis tol-so simplify the mechanism that it can be moved over the floor'without .the expenditure of reat exertion, and when so'movcd, will fee clean water to the scrubbing brushes and thereafter scoo up the dirty water left by the brushes a (i deposit it in a tank for the reception of dirty water so that after the passa e of the ma- -chine the floor will be scrubbe and wiped so that furthercleaning is unnecessary.

The invention further contem lates the y employment of waxing devices an polishers in place of scrubbing brushes, device, ferred from `a scrubbingvdevice into a polishingrdevice as occasion requires.

he invention relates tothe means employedrfor actuating the several brushes, to the'rotary squee eeapparatus for removing the water from t e floor, to the construction whereby the and arrangement of the framework of thev machine, to the arran ement and construction of the tanks for c ean and dirtywater, and to the machine as a whole and to the individual parts thereof.

The invention consists in the features of construction and combination of Aparts hereinafter described and claimed.

In-.the drawings Figure 1.1s a side elevation of the machine, showing the outer wheels partially broken away, and revealing the gear mechanism; Fig. 2 a side elevation of the plates comprismg the sides of the framework; ig. 3 a longitudinal sectional elevation of the'mecha'nism as a whole Fig. 4 a top'or plan view of the same; Fi 5 a cross sectional view taken on linel5-5 o Fig. 4 looking in the di-` rection ofthe arrow; Fig. 6 -a cross sectional view taken on line 6-,6 of Fig. 4 lookin in the direction of the arrow.; Fig. 7 a detail of the s ueegee clutch; and Fi .f8 a detail shown t e detachable wax hol er.

he device comprises -a pair of. rubber forward wheels 8,.and a similar pair of without further change, can be transl swing down to I lprojecting ends of the shafts 16 and 21.

vrubber tired rear wheels 9, which wheels are mounted upon stub shafts 10 and 11 respectively, which are fixedly mounted within the side plates 12, which serve as a framework for the machine. The side lates are suitably spaced and connecte together by means of a plurality of cross tie rods 13 'i which, in combination with the side plates, furnish a ri 'd open framework for the machine.` Eac of the forward wheels 8 is provided on its inner face with a circular rack 14, provided with gear yteeth on its inner and outer faces, the inner teeth of which mesh with a brush gear wheel 15, which is mounted upon a shaft 16 carrying a rotary scrubber 17 o which is located b`ecylindrical formation,

The shaft 15v is cartween the side plates.`

' ried by a forward adjustable hanger 18, and

is ada ted to move within a slot A19 in the side p ate, which slot is cut substantially concentric with the inner teeth of the circular rack, so that therotary scrubber can be adjusted to varyin heights with respe'ct to the floor level' wit out throwi the gear wheel 15 'out of mesh with the rac j vThe forward brush 17 cooperates with the rear brush 20 mounted on a shaft 2.1 carried by a rear hanger 22 and movable within a slot 23, which permits vertical adjustment. In order to permit the rotary brush shafts to lbe removed from the frame and permit the substitution of brushes of a different grade, or of rotary floor polishers, the side plates of theframe, adjacent to the lower ends of slots 19 and 23, are provided with hinged portions 24 and 25 res ectively, which can permit t e withdrawal of the At the front end of the machine is located an auxiliary scrubber shaft 26 which is carried by brackets 27, which forwardly roject from and are adjustably secured to the forward end of the main frame; and the auxiliary scrubber shaft 26 carries, at its ends, a pair of auxiliary scrubbers 28, which are locatedimmediately in front of the forward wheels and serve Ato permit access to be had toV corners or other restricted areas of floor surface, andalso serve to. scrub the floor area traversed by the wheels. The auxiliary shaft 26 is provided with a ,gear wheel 29 which meshes with a gear wheel 30 mounted upon apower transmission shaft 3-1, which is 'ournaled' to the forward end of the main ame. The shaft 31, in additionV to the gear wheels 30, .is provided at each end with` a' gear wheel 32, which meshes -with the exterior teeth of the circular rack 14,. whereby all of the rotary brushes will be slmultaneously revolved as the machine is moved over the floor. Immediately above the two main brushes is located a'clean water tank 34 provided with a trough shaped channel or depression 35 in its bottom, from which water 1s discharged through openings 36 adjacent to the rotary scrubbers.

In order to ermit the device to be usedg for polishing, t e bracket arms 27 are adapted to have detachably secured thereto a transversely extending box or casing 37- are clamped, or otherwise held wit in the The rotary s ueegee is proafts or trunsurface thereof. vided, at itsy ends, with stub s nions 42, which are carried by and journaled within the side plates 43 of a movable frame 44, which latter is held elevated to a suitable degree above the main or fixed frame by the action of springs 45 against the upward ressure of whic 1 the movable frame can be owered by exerting pressure thereon through the medium of a handle 46, which handle is justed with respect torthe xed ,correlation with one another.

secured to a bracket 47 located u on the top of the movable frame by means o a bolt and nut 47, so that 4by loosening the nut the handle can be-moved to diderent angles as occasion requires. When it is desired to depress the movable frame which carries the.

squeegee, a downward pressure can be exerted on the handle in addition to a forward or driving pressure, which can be easily accomplished byfbearing down on the handle with one hand while pushing the machine forward with the other. The bracket 47 is held in operative position with res ect to the fixed frame by means of a air o obliquely extending side arms 47b W ich are pivoted at their forward ends tothe fixed frame by means of pivot pins 47C, and are pivoted to the bracket 47 by means of pins 47 ientering slots 47", which arrangement per mits t e movable frame to be vertically adframe and at the same time holds the parts .in suitable The movable frame is provided with a plurality of outwardly` extending. studs 48, which enter slots 49 in the wa of the main frame, which serve to guide the up and down movement Vof the movable frame.v The shaft 42 has loosely mounted thereon a gear wheel 50 -fromf'the device for discharge o with a slidable clutch 52 located onthe shaft 42 inside of thegear-Wheel, which clutch can be moved'into engagement with the gear by means of a rod 53 pivoted to the movable frame at the point 54 and adapted to be actuated by a hand lever 55 secured to the handle or in any other suitable manner.

The fixed frame has rearwardly extending therefrom channeled arms or brackets 56, which carry a dirty water tank 57, provided with an open mouth 58 in its front side over the lip of which is hooked a curved dasher.

plate 59, the lower end of which is adapted to contact the floor, and the face of which is adapted to coperate with the rubber blades or paddles of the rotary squeegee, which force the dirty water up along the dasher plate and into the mouth of the tank. In orer to concentrateA the water against the squee ee a pair of forwardly divergmg rubber faced bars 60 are provided which roject'outwardly from'the sides of the scru ber imme diatel behind the rear best s own in Fig. 4.

In use, when it' is desired to'scrub a oor without taking up the water, the squeegee clutch is drawn device moved back and fort which causes the scrubbers to operate without moving. the squeegee, which latter, being mounted within the spring supported movable frame, will be elevated above its acting position until pressure is brought to bear upon the handle which forces' down the movable frame against the tension of the spring and brings brushes thereof, as

lthe blades or paddles of the squeegee into position to act against the floor surface after which the clutch is thrown intoengagement, which causes the squeegee to revolve and carry up the dirty water into the tank provided therefor.

can be varied by adjusting the hangers to different degrees, which serves to permit regulation of the tension or ressure exerted by the bristles'against the oor surface and at the same time permits the brushes to be adjusted to com the bristles. brushes, in like entirelyremoved from the scrubber. The dirty water tank can be readil removed the water by unhookng the dasher plate from the li o -the tank and thereafter drawing it bacli out of enga ement and the The position of the main rotary scrubbers with respect to the iioor level ensate for wearing away of he forward supplemental. manner can be adjusted, or.
